Compressed air is an expensive energy source and should therefore be used responsibly. To recognise possible savings, measuring instruments for precise measurement of compressed air consumption is required, improving energy balance and saving costs. Compressed air is also needed on a large scale in municipal sewage treatment plants for their aeration basins. The demand represents a significant if not the largest share in the energy consumption of the municipality providing great potential for savings. Compressed air and electricity consumption can be localized and reduced through an exact consumption measurement. This is an essential contribution to the company’s energy management and can be part of the certification.

Höntzsch’s thermal flow sensor TA allows direct gas mass flow rate measurement without additionally requiring pressure and temeprature sensors. It is very small and therefore not being a big obstruction in the pipeline making the pressure loss quite negligible. The small time constant of 1 s enables accurate measurement with high temporal resolution. Our thermal sensor TA is suited for pipelines with an inside diameter starting at 8 mm.

Additionally to compressed air other gases such as propane, butane or hydrogen can be measured as well. They are also very valuable gases, their consumption a cost relevant factor and are important for energy management.

Measuring data is usually transmitted via the power interface (4 … 20 mA). M-Bus interface is also available as well as transmitting data via WIFI.     

For transmitting quantity pulse or limit value there’s also a digital outlet available.
